python datetime swapping day month

I have a date time object that looks like:

2015-31-12 00:34:00

where the second element (31) represents the day and the third element (12) represents the month. How do I swap day and month so that the date looks like:

2015-12-31 00:34:00

You'd parse the string into a datetime object then format it again back to a string:

from datetime import datetime

result = datetime.strptime(inputstring, '%Y-%d-%m %H:%M:%S').strftime('%Y-%m-%d %H:%M:%S')

Demo:

>>> from datetime import datetime
>>> inputstring = '2015-31-12 00:34:00'
>>> datetime.strptime(inputstring, '%Y-%d-%m %H:%M:%S').strftime('%Y-%m-%d %H:%M:%S')
'2015-12-31 00:34:00'

So the datetime.strptime() parses the string given a pattern, where you specify that the order is year-day-month, and datetime.strftime() formats it back to a string, with the day and month positions swapped.

Use .strftime('%Y-%m-%d %H:%M:%S').

For example:

from datetime import datetime
formatted_date = datetime.today().strftime('%Y-%m-%d %H:%M:%S')
